Background
     The Catawba-Wateree CHEOPS (Computer Hydro-Electric Operations and Planning Software) model was developed as a study tool during the Federal Energy Regulatory Commission (FERC) relicensing of Duke Energy's hydropower projects in the Catawba River Basin. Duke Energy has allowed the State to use their model to evaluate basin-wide water resource issues. Information on the model can be found in the CHEOPS User's Manual .
     The model incorporates operational strategies that were developed during the lengthy process of negotiations between stakeholders during the FERC hydropower relicensing process. A component of these operational strategies is the Low Inflow Protocol (LIP), which establishes procedures for reductions in water use during periods of low flow. A purpose of the LIP is that all parties with interests in water quantity would share responsibility to establish priorities and conserve the limited water supply.
     The model uses a 15-minute time step. The output is in both a 15-minute and daily time-step. Only the daily values are being provided to simplify and improve response time for doing analyzes and summaries.
